SPEED REGULATING AND CONTROLLIiNG DEVICE.

Application filed June 4, 191;.

To all whom it may com-cm lie it known that l. Tuoims Swuitoxs, acitizen of the l nited States. residing at Dayton. in the county ofMontgomery and State of Ohio. have invented certain new and usefulImprovements in Speed ltegulat mg and (ontrolling l)evic and I dodeclare the following to be a full. cleail and exact description of theinvention. suclras will enable others skilled in the art to 'lll('ll itappertains to make and use the same. reference being had to theaeconnianying drawings. and to the letters and figures of referencemarked thereon. which form a part of this specification.

My invention relates to speed regulating and controlling mechanisms formoton driven \tlll('lt more particularly automobiles. motor-trucks andmotorcycles. Owing to the new uses and purposes which the .tion toprovide effective and practicable means for regulating the speed ofvehicles of the character named in a more convenient and satisfactorymanner than is possible with the present method of placing watchmen atgiven distances apart, provided with stop watches. for the purpose ofascertaining the speed of such vehicles.

The invention comprises means by which the driving power of a vehiclewill be automatically shut off when the speed, as shown by an indicator.has reached the highest point to which the controlling mechanism hasbeen previously set, it being understood that some person in authorityhad previ-" ously set the indicating and controlling mechanisms to someparticular rate of speed, For example, were the controlling mechanism tobe set to a speed of say twenty miles an hour. when the speed indicatorhand reached that figure. the power would be instantaneously shut offand the speed of Specification of Letters Patent.

the vehicle correspondingly reduced, it bein'; a mechanicalimpossibility for the vehicle to attain a higherspeed than that at whichthe indicating and controlling mechanisms are set.

A further object of the invention is to provide means for locking theindicating and controlling mechanisms at any desired point from sixtymiles an hour, for eX- ample, to a stand still position. The importanceof this feature will be readily recognized. as it prevents a theft ofthe vehicle or its use by unauthorized persons, while enabling the.owner thereof to maintain absolute out-of-sight control over the driveror chauffeur who might, as is too often the case. be possesse'dof thespeed mania, and thereby relieving the proprietor of a heavyresponsibility.

A further object of the invention is to provide means by which municipalauthorities may, in the interest of public safety, as-

tions between said respective mechanisms.

sume absolute control of the speed of any or all motor-driven vehicles.The value of so this feature is almost beyond estimation, as in theevent of a too'frequent abuse of less drasticregulations. The offendermay be hobbled, so to speak, by having his vehicle locked out by orderof the proper anthemties at such rate of speed as in their judg ment theoffentlegshould be allowed to rim.

These and other objects incidental thereto will appear from the,following description of my invention in detail. Preceding suchdescription, reference is made to "the accompanying drawings as follows:7 I

The hand 13o isinstrumental in hidicating the highest speed attained my the automobileduring any particular time or trip. The segment gear 2 is in mesh with apinion 4:2 mounted on a shaft ll journaled ii the frames and 4. Alsomounted on the shaft 41 is a gear 42 in mesh with a gear 4 attached toone end of a shaft ll mounted in the sleeve it. The gear t is an important element in that it imparts movement to the main indicator handthrough the shaft H and also supports the brushes through which theelectric circuit is controlled. ()n the end of the shaft H opposite thegear 43. is the main indicator hand l3 which oper ates in connectionwith the dial to indicate the sp ed of the automobile. The dial i andhand i are of such a size that the speed of i!" automobile will be indiated to persons at a considerable distance and others than pa s r-tigersin the car.

The means for preventing the car attaining a higher speed than the ratedetermined bv some one having authority. is as follows: The sleeve to towhich reference has been made has a gear 47 attached to it which gearcarries an insulating disk 54. Also mount d on th sleeve 4 is a drum 4%provided with indications it) which are viewable at the front through anopening 50 and at the side through openings Til. The indications on saiddrum viewable. through the openings 50 and 51 designate the speed limitto which the device is set. The said speed limit indicator drum l8 isrotated bv means of a gear 32 mounted on a shaft 33 journaled in theframes 3 and 4. The gear 52 meshes with gear 47 on sleeve it). means forrotating the shaft 53 will he hereinafter described.

The means for rendering the automo ile, inoperative when the machinepasses the speed limit to which it has been set is as follows:lheinsulation disk 54, mounted. as before stiited. on the gear 47. isprovided with a conductor ring having a pocket in; which receives anextension of said insulation disk 54. Adapted to press against theconductor ring 55 is a brush 57 carried by the gear 43. The said brush.17 forms the ground end of the sparking circuit of the automobile. Thecircuit is completed by the, brush 57 through the agency of a pawl 3dpivoted at 59 to an insulated block (30 The said pawl 58 is providedwith a lead wire 51 which is connected into the sparking circuit. henthe said brush 57 is in engagement with the conductor ring 55. thesparking circuit will be completed but when iiaid brush 57 rides uponthe insulation in the pocket 56, the sparking circuit will be hrokcn andthus the automobile wil be rendered inoperative.

The

It is to be understood that the present illustration shows the device asconnected into the ignition circuit of an automobile. The collcctora'ing.33 is: provided with a plurality of recesses t'r. which receive thenose 11:; ot' the pawl 33 which is instrumeie tal in holding thecollector ring .35 in any one of its set positions. The space betweenany two of the recesses 1'2 represents a speed variation of live miles.l\s shown in the drawings. Figs. 1 am i. the instrument is set to aspeed limit of twenty miles and it will be seen that when the fly-balls17 are revolved to an extent corresponding in velocity to a speed oftwenty miles an hour, the brush 5T will ride upon the insulation disk 34extending into the pocket 56. thereby breaking the electric circuit. Toindi ate to the driver when he is approaching the speed limit. anaudible indicator in the form of a buzzer tH- is provided in an elecstrical circuit of one end of which is grounded through a battery (at andthe other end of which is connected to a brush (3? whiclr is carried onthe gear l and in engagement with a collector ring H mounted on the in.-sulation disk Til. The collector ring (38 is provided with an offset(tit adapted to be engaged by the inner brush 71) prior to the time thecar reaches the speed limit. The brush 70. like the brush 37, is mountedon the gear lit and is normally in engagement with the insulation disk("i-l thereby hormally maintaining an open circuit through the buzzer ilaml the battery 36. The brushes .7? and T0 are for convenienceillustrated in Fig. 3 as being free from the gear 4 but it will be bornein mind'that the said brushes are carried by said gearfas appears .inFig. 6.

The means for setting the speed limit indicating drum 4S and theinsulation disk 5+ is as follows. as shown in Fig, 2: Connected to ashaft 53 bv means of an inter mediate flexible shaft 71 and universaljoints 72 is a shaft 73 which is journaled in the casing 74 having afront plate 75. The casing 74. for example. is conveniently mounted onthe dash of the automobile and the front plate 75 thereof is providedwith a dial face 76 which is read in connection with a hand 77 extendingfrom a finger knob 78 on one end of said shaft 73. By rotating the/knobTS'and reading from. the

hand 77, theposition. desired for the indicating drum 48 and insulationdisk 54 may be determined. It will now be noted that when the drum 48 isset to indicate zero through the front and side openings 50 and 51 inthe casing 1. the outer brush 57 will be in engagement with theinsulation in the pocket 56, thereby rendering the vehicle inoperative;and it is to he further understood that in this position the insulationdisk 54 will also be in engagement with the inner rush T therebymaintaining-an open or brokei1.ei|-euit for the uzzer bl.

The setting mechanism just described may be locked in the above positionby means of a permutation lock as now described. This lock isinstrumental in locking the \chicle in a standstill position and to suchmaximum rate of speed as may be determined upon. at one and the sametime. and to this end said lock is necessarily composed of two sets ofcombination ratchets and tumblers operated by the same thumb knobs butcapable of being set to two separate and distinct combinations. one forwhat may be termed the high speed and the other tor a stand-stillposition. For example. the vehicle may e locked to a maximum speed oftwenty miles an hour under the high speed combination of say SL537. andto a stand-still position under the low speed combination of say ll4.5.32. By such provision it will be seen that the vehicle may be lockedor unlocked to or from an inoperati\e position by setting thecombination Ill 1.7K: iudepeudent of the vehicle being locked to anyparticular maximluu rate of speed under com ination 4. 7 and it isfurther obvious that without a kno\\'ledgc of the high speed combinationthe vehicle can be operated at no higher speed than that to which it maybe locked out. This renders it possible for the prte. prietor or theauthorities to maintain absolute control of the \chicle y setting andlocking it to whatever rate of speed it may e desired the \ehicle shouldrun.

The foregoing" results are achieved as follows. as shown on SheetMounted on the setting shaft T l within the casing it is a disk 71'provided ith a plurality' o recesses M which cooperate with a su'ing-eoutrolled pawl i l to hold uld tlislv' T9 itl any particular setposition. i\ny one of the recesses 50 mav receive a locking bolt 1secured to a disk 2 slidably mounted upon the shaft 73. When the bolt #1lies within any one of said rece ses NU. the knob Ts is prevented frotnbeing rotated. The disk 82 eanryiug the bolt 1 is lnou-tl along theshaft T3 to remo\c thc bolt l out of any of the recesses so by resilientarms 32 provided with linger pieces RI \\hich extend through openings H3in the side of the casing 71. The disk T9 is normally locked by the boltH1 within one of the recesse t held in position by tum lers so. whichare adapted to engage projections HT on the disk The tumblers so arettlt'll pro\ ided with a recess 89 which permits the disk 5; to beshifted when the combination tumblers are properly set. When thecombination of the tumblers 96 is properly set. the said disk 82 canthen be shifted to an extent sufficient to permit the bolt tittforelease the disk 79. thereby permitting the insulated pocket 56 in thedisk 34 to be advanced from engagement with the brush 5? which in turnpermits the vehicle to be operated or driven. At this time. the drum tmay also be set to indieate whatever speed the operator may havedetermined upon. The disk 91. which is the speed limit disk. is similarin construction to the disk 71) and is provided with recesses similar torecesses 30 on disk 7! The said disk 01 is freely mounted on the shaftT53 and is held in a set or locked position by the bolt 91 in the samemanner as is the disk 7 but. unlike the disk T9 which is rigidly mountedon shaft 73. it is actuated in its forward movement by a pin so on thedisk 79 which engages a pin 94) on said disk "I and is returned to anormal position by a spiral spring 94 fastened at one end to the disk )1and at the other end to a pin 91 on the rear wall of the casing T4. InFig. 17 the pin f tl is shown in the path of the pin #11 on the disk Ti'hen it is desired to lock or unlock the disk 91. the process of lockingand unlocking the disk 79 is repeated onl a ditl'erent set ofcombination tmublers being used. the tumblers 95 being brought intoplay. 'hen the combination ofthe tumblers 95 are properly set. theboltcarrying disk H2 may be moved along the shaft T3 to an extent whichwill permit the bolt H1 to enter or be removed from the recess 92 in thedisk 91. When the disk 91 is in an unlocked position. it may be set byrotating the knob To. the said disk 91 being actuated by the disk 79through the agency of the pins 89 and 90. before referred to. The properposition of the disk 9 may be ascertained by noting the position of thepointer 77. After the smiodisk 91 has been set. it may be locked insuch'position by shifting the disk 82 to bring the bo;lt 81 into one of therecesses 92 of stiid disk 91.

The combination tumblers 8t) and 95 are set as follows: In the'presentinstance. there are six combination tumblers St having twelve digits tothe combination number. These tumblers 86 are secured to sleeves 98provided will. disks 99. The disks 99 are provided "with ratchets 100which are in operative relation with spi vingcontrolled pawls 101mounted on disks 102 which are part of the spindles 103. The spindles1053 extend through the front/ plate 73 of the casing H and are providedwith thumb knobs 10.4 by means of which said spindles 103 are rotated.as shown in Fig.

9. 'hen the spindles 103 are rotated. the

ride over their ratchets 100 and 105 during the setting of thecombination, these ratchets and pawls being instrumental during theselecting of the combination. The disks 102 are provided with recesses107 which receive the ends of spring-click pawls 108. The pawls 108 areinstrumental in audibly indicating the extent of. revolution imparted tothe spindles 103 by the knobs 104. One of the recesses 10? in each ofsaid disks 102 is deeper than the others in order to permit the normalposition of the spindles 1015 to be ascertained. The combination is setby retating the spindles 10 3 a definite number of clicks from thenormal position. 'hen any one of the tumblers 50 or 05 has been properlyset, its recess 58 will lie opposite its respective projection ST of thedisk 82. selecting the combination numbers of the tumblers b6 and 05,the previous combination is first set and the tumblers 80 or 95 arelocked by shifting the projections ST into recesses which locks thetumblers S6 or 05 against rotation. The combination numbers may then beselected by rotating the knobs 101, said knobs being rotated in onedirection to select the combination for the set of tumblers 80 and inthe other direc tion to select the combination for the set of tumblers05. During this selection of the combination, the pawls 101 and 106 rideover up ratchets 100 and 105, thus permitting the relative positionbetween the recesses 88 and the deeper notches 107 to be adjusted. Toprevent the set combination being thrown out by unauthorized personspressing the pro ections 87 of disk 82 against the tumblers S0 or 95,the arms 83 are made resilient to prevent suflicient pressure beingexerted on said tumblers 86 or 95 to force the pawls 101 and 100 to rideover their ratchets by rotating the knobs 104. The casing 71 and faceplate a1" held together by pins 10'.) which are in operative relationwith the combination tumblers 86 and 9:3, \Vhen the recesses 88 of thecombination tumblers 86 and 95 lie opposite the pins 109, the casing 71may be removed from the front plate 75. The combination number forunlocking the casing may be ascertained by adding to each digit of thecombination number of the tumblers 86 andQT) one-half the number of thenotches 10? in each disk 10; which in this case is twelve. \Vhen the caror automobile is placed out of operation,

the drum 48 is returned to a normal position by rotating the thumb piece78 backward to a position where the hand 77 indicates ZQIO on the dial70. Astop is provided to indicate this position which consists of a pin110 mounted on the gear and a pin 111 mounted on the frame 1', see Figs.1 and :1. in which stop pin 111 appears in the path of pin 110. Justprior to the time that the drum 42% rea hes its highest set, or

sixty mile, position, the pawl 38 is released from engagement with thesegment ratchet 37, Fig. 4', which permits the band 210 which indicatesthe attained speed, to return to a Zero position under the influence ofthe spring 112. The pawl 38 is disengaged from the ratchet 37 by a pin113 mounted on a (rank 114 attached to the shaft 5 The pin 113 isadapted to engage the extension 11.3 of the pawl 35.

The mechanism for the mileage indicm tions shown in the front and rearelevations, Figs. 1 and 1, is not shown in detail but this consists of awell known dial form of adding mechanism which it. has not been deemednecessary to illustrate. Provision is. however, made for theincorporation of these devices. Furthermore. i do not wish to beconfined to the present illustration in the matter of etl'ecting theelectric circpit, as it is obvious that the brush 5?, may beinstrumental in interfering with any type of electric circuit to renderthe vehicle inoperative, whether driven by electric or gasolene motivepower.

Having thus described the various mech anisms and functions of myinvention, its operation is as follows. With the device mounted upon anautomobile, for example, and the controlling mechanism resting in alocked position as shown in Fig. 0, Sheet Ii, the operation preparatoryto moving the vehicle consists of, first, setting the high and low speedcombination tumblers 05 and so to their proper positions with the lugsa? and notches 88 in alinement, second, shifting the locking bolt 81 outof engagement with disks T9 and 9land then setting, the indicating drninit"; to whatever position may be determined upon byturning the knob TH.From the drawings and description, it will be understood that theinsulated pocket 56 i will then have been advanced out. of engagementand ahead of contact brush 5?. thereby rendering the vehicle ready foruse. If after setting said vehicle in operation. it should be desired torun at a higher speed than the indicating drum 18 had been set to, saiddrum would again have to be advanced in its position for the reason thatwere the speed to be increased without advancing the indicating drum.the contact brush 5? would overtake the insulated pocket 30, and throughsuch engagement eli'cct the sparking circuit, as heretofore shown anddescrib d. The vehicle would not be brought to a standstill position,however. as the force of its motion would carry it forward. while brush5?. under control of the fly-bails 12', would fall back out ofengagement with. insulated pocket .16, thereby permitting of another impulse of motive power. With both sets of combination tumblers set totheir proper positions, and the int-king hoit 81. withdrawn fromengagement with disks 79 and 91, as

mentioned inthe starting operation. it is then within the power ol' theoperator to set the indie: tor drum tn to the full eapaeity of theeoutrolliug meehanism whieh. in the drawings. shows sixty miles an hour:hilt. it it be desired by anyone in authority that a lower rate ol speedbe maintained. the same would be aeeomplished by. first, set tinu' thehigh speed eombination tumblers to their proper position. seeond.rotating the indit-ator drlun 45' to whatever lower rate of speed may bedetermined upon and then shitting the ltlt'ltlllg bolt 51 intoengagement with l'tl fi'i 3 in disk 91.

From the deseription and drawings of my invention. it will be apparentthat ehanges and modifications of the same-may be made withoutdeparting, from the objects and purposes thereof whit-h are to provide;means for regulating: the spe d of automobiles. motor-e \'eles. and thelike. I, therefore, do not wish to be eontined to the exact eonstruetionand arrangement of parts of the mechanism.

A feature of my invention which I wish to emphasize. and one that is inradical 1 09' trust with the ordinary speedometer now generally in useon automobiles. is the large and prominent t'lotkt'at'ed indicatingdirt? direetly in front of the vehicle with the ti}; ure indieating: thespeed limit in t'trs irg eolor.
